Operations of Polynomials

Add the polynomials.
(2x + 5y) + (3x - 2y)

• 3x + 5y

• 5x + 3y

• 5x + 7y

• 7xy + 1xy

Subtract: (2a² + 5a + 3) -(a² - 3a - 4)

• 3a² + 2a - 1

• a² + 8a + 7

• 3a² + 8a + 7

• a² + 2a - 1

Combine like terms:

8x³y + 3x²y + 4xy + 5x²y + 2xy + 7x²y

• 8x³y + 8x²y + 2xy

• 11x³y + 15x²y + 8xy

• 8x³y + 15x²y + 6xy

• 23x²y + 6xy

Add: (3x² + 2x + 1) + (2x² - 4x - 5) + (3x - 1)

• 5x² + 6x - 7

• 8x² - 3x - 5

• 5x² + x - 5

• 6x² + 8x + 5
